[KB-030] My trackball only moves vertically, not horizontally. What is wrong?

Product: Tankstick / Tri-Mode PCB | Platform: PC / All | Confidence: Medium

Answer:

If your trackball only moves vertically (up/down) but not horizontally (left/right), try these troubleshooting steps:

Check the Horizontal Disabler Button: Some trackball PCBs have a "horizontal disable" feature used for golf games (like Golden Tee) that only require vertical movement. Check if this feature is accidentally enabled.

Try Firmware Update: Download and install the latest Tri-Mode PCB firmware: http://www.xgameroom.com/service/ServiceFiles/Tri-mode%20PCB/Tri-Mode%20FW%20V19.4%20Update.zip

Hardware Component Failure: If the above steps do not resolve the issue, it may be caused by a failed opto transistor or BJT on the trackball PCB. The original Sharp components are discontinued, but EE-SX1081 has been identified as a compatible replacement part.

Note: Xgaming does not provide internal schematics for the trackball assembly or the horizontal disabler circuit. If you have an older Tankstick (pre-Tri-Mode), you may need to upgrade to the Tri-Mode PCB for full functionality and support. """
